鋼管 規格表
2種規格資料
鋼管是用於配管、結構件和流體輸送等多種用途的圓形截面鋼產品。碳鋼管(KS D 3507)最廣泛用於水、蒸汽和氣體管道；不鏽鋼管用於食品、製藥和半導體等需要耐腐蝕和衛生的場合。壁厚按Schedule號選擇。
常見問題 (FAQ)
What is the difference between carbon steel pipe and stainless steel pipe?
Carbon steel pipe (SGP) is cheaper and suitable for general piping but susceptible to corrosion. Stainless steel pipe (SUS304/316) excels in corrosion resistance and hygiene for food, medical, and chemical piping — at higher cost.
What is the difference between pipe size notation A and B?
A (mm) and B (inch) are different notations for the same pipe. E.g., 25A = 1B (approx. 1 inch). These are nominal sizes, not actual bore — check the spec table for actual OD and ID.
How do I choose between SUS304 and SUS316 piping?
SUS304 suits general corrosion environments (water, air, mild acids). SUS316 has added molybdenum for superior resistance to chlorides, brine, and strong acids — used in marine and chemical plants.
